SUPPORTING DEVICE FOR DAMPER-CHAINS OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 778,285, dated December27, 1904. Application filed April 13, 1904. Seria1No-203,600.

To LtZZ whom it may concern:

Be it known that I, GEORGE H. TARLnToN, a

' citizen of the United States, and a resident of Watertown, in theCommonwealth of Massachusetts, have invented a Supporting Device forDamper-Chains or the Like, of which the following description, inconnection with the accompanying drawings, is a specification.

In running the damper-chains from furnaces many practical difiicultiesare encountered because of overhead beams, chimneys, pillars, juttingcorners, &c., so that much expense and labor and often considerableingenuity are required to get the proper alinement and freerunningdirectness of the chains from the dampers, and accordingly to obviatemost of these difficulties Ihave .provided a special self-alining chain-oarrierin the form of a baseplate adapted to be strongly secured inany position to a beam, wall, or ceiling and carrying a swiveled arm soshaped and located as to give the strongest resistance in combinationwith the base-plate, said arm atits free end having a pulley located atone side of the pivotal axis of the arm, and in connection with thecentral or meeting point of theseveral chains a third pulley is locatedin vertical alinement'with two of these tangential pulleys, as I'termthem, all as will be more specifically stated in the followingdescription, referring to the accompanying drawings. The result is thatthe ingenuity, labor, and expense above referred to become no longernecessary in order to meet awkward or special situations, as no matterwhat the directions or situation may be my special apparatus receivesthe chain from any direction and automatically alines itself thereto andto the direction in which the chain or chains are led, all withprecision, strength, and permanence.

In the drawings, in which I have illustrated the construction and use ofmy invention, Figure 1 1s a View in s1de elevation of one emproperly adiagram, illustrating the adapt.

ability of my invention to different places and requirements inconnection with furnacedampers.

It will be understood, still using the same illustration of damper-Work,that the strain brought by a chain upon a pulley is usually downward andlaterally, and accordingly I have located the pulley a, referring to itssimplest form, Fig. 3, at one end of a flat baseplate a, so that therearwardly-extending plate thereby receives and resists all strains tothe best advantage, and also, as the direction of the lateral strain orpull of the chain is liable to vary, I increase the width of thebase-plate a rearwardly, making it triangular, as herein shown. Thepulley a is'journaledin the free end of a short curved arm a bifurcatedto receive it, and the opposite or upper end of said arm a is swiveledon a short stud or pivot post a and a reference to the drawings showsthat said pivot-post a is in a plane approximately tangential to thepulley, so that a chain passing vertically to the latter will be insubstantial alinement with said pivot-post. This, in connection with theshort compact constructiongives great strength and insures certainty ofposition. ment brings the two pulleys, as indicated'at a a, referring tothe construction shown in Figs. 1 and 2, into proper relation to receiveopposite chains 6 6 and transmit them together to a thirdchain 6 forconnecting the entire system to a common operating-stand 6*, as willpresently be explained. For such an-arrangement I mount on thebase-plate a a long hanger having a swiveled arm a at its lower end, inwhich is journaled a pulley a swinging very nearly into verticalalinement with the stud a so that no matter what direction the chains 6b may come from the pendent pulley a will always be in proper positionto receive the common chain 5? therefrom.

at cl and a check-damper at d, the chains 6 b therefrom passing overopposite single-pulley devices to a central double-pulley device Alsothe above tangential arrange,

and thence being united at I) and passing to a hanger-pulley a andfinally to the controlling-stand 6*.

.In Fig. 3 I have shown the hanger-pulley 0 provided with its ownbase-plate a for special uses.

As already intimated, I do not restrict my invention for use withdamper-chains, as it is applicable to various situations and kinds ofWork, nor do I restrict myself in all respects to all the details aboveset forth, as will be evident from the following claims.

Having fully described my invention, what I claim, and desire to secureby Letters Patent of the United States, is

1. A device for damper-chains and the like, comprisingahorizontalbase-plate,fr0m which projects perpendicularly a short pivot-post, ashort curved arm swiveled about said post, and a pulley journaled in thefree, outturned end of said arm and having the inner side of itsperiphery approximately in vertical alinement with said pivot-post.

2. A device for damper-chains and the like, comprising a base-platehaving at one end a vertical pivot-post, the sides of said base-plateflaring from each other rearwardly from said pivot-post for takingstrains in alldirections, a short laterally-extending arm swiveled tosaid post, and a pulley journaled in said arm.

3. Adevice fordamper-chains and the like, comprising a base plate, ashort pivot post depending therefrom, a plurality of shortindependently-swinging arms swiveled on said post, and a pulleyjournaled in the free end of each arm.

4:. A device for damper-chains and the like, comprising a base-plate, ashort pivot-post depending therefrom at one end, a plurality of curvedarms swiveled on said post, a pulley journaled in each arm, a hangerdepending from said base plate adjacent said post, and a lateral arm andpulley on the lower end of said hanger, the outer peripheral edge ofsaid last-mentioned pulley being approximately in vertical alinementwith said short pivot-post.

In witness whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

GEORGE H. 'llAhLE'lON.
